Ketchump is right.
As an once avid RC builder, I can confirm. More RCs you build, less likely you will get better ones so if you want to build high quality RCs, make sure to build them early. If you don't have any RCs, you are more likely to get insane ones like 100/100. As you build more, you will see less extreme RCs. After 3 insane RCs, you will mostly see ones in 70s. After a couple more you will be down to 50s and so on. I think it caps out at around 30s?
